1) What is the daily profit of the shopkeeper before the price increase? - 160*(2- 1.5)= 160*0.5=80

(2) After the price increase, the shopkeeper wants to make a profit every day 120 yuan. If the price department stipulates that the operating price should not exceed twice the cost price, what is the sales price of each cage of steamed buns?

If the unit price is 2.5 yuan-(2.5-2) * (160-20) = 0.5 *140 = 70 yuan.

If the unit price is 3 yuan-(3-2) * (160-40) =1*120 =120 yuan.

If the unit price is 3.5 yuan-(3.5-2) * (160-60) =1.5 *100 =150 yuan.

If the unit price is 4 yuan-(4-2) * (160-80) = 2 * 80 =160 yuan.

He should set the price of each cage of steamed buns as 3 yuan.

(3) After the price increase, if the shopkeeper wants to get the highest profit every day, please help him set the sales price and figure out what the maximum profit is.

The unit price is 4 yuan-(4-2) * (160-80) = 2 * 80 =160 yuan.
